Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus and a method for converting a hardware using a JavaScript language,

The present invention relates to a technique for converting hardware using a JavaScript language, and more particularly, to a method and system for converting a hardware into a logic circuit corresponding to a purpose of a function using a reconfiguration hardware in a web application written in JavaScript, To improve the processing speed of the image processing apparatus.

Most browsers that run web applications have a JavaScript engine for running JavaScript applications. Typical JavaScript engines include Google's V8 engine, Webkit project's JSC (JavaScritCore) engine, and Mozilla Foundation's Firefox browser, Spidermonkey.

Google's V8 engine is written in C ++ code and supports a variety of hardware platforms, including X86, X64, ARM, and MIPS, and can translate JavaScript code into AST format without any bytecode translation and can be run directly through an interpreter. It also uses various techniques of JIT compiler technology for machine code optimization. Typical features include Hidden Class and Inline Caching technology.

Webkit's JSC engine is primarily built into Apple's Safari browser and is available as open source as the V8. The JSC engine consists of a lexer, a parser, an interpreter, and a just-in-time compiler (JITC). When byte codes are output through the parser block, . In JITC, the baseline JIT, DFG JIT, FTL JIT, etc. are configured to operate by optimizing the machine code step by step according to the optimization level.

Currently, various technologies have been proposed to improve slow performance, which is a big problem in web applications. SIMD (Single Instruction Multiple Data) instruction, and multi-core multi-thread and multi-core WebCL.

First, the SIMD technique is described as follows. SIMD, which can process multiple data using a single instruction, is a technique widely used in Intel as well as ARM. By using SIMD, scalar operations can be extended to four or eight vector operations.

The second is to use multithreading with multicore. Currently, most JavaScript engines operate as a single thread, which is a way of dividing and dividing functions that can be separated in stages into several threads in the engine. For example, assuming that the lexer, parser, and interpreter are running on thread 1, there may be a way for JITC to run on thread 2. This technique is possible because if the JavaScript engine has a function that has a large number of iterations at runtime, it determines whether to activate the JITC by counting the number of executions. At this time, Is generated, the corresponding machine code is sent back to the thread 1, thereby reducing the compilation overhead.

Third, WebCL technology is a heterogeneous computing software technology that uses parallel techniques. WebCL is the API standard for OpenCL's Web version of general computing. Since its inception as a prototype version since 2011, WebCL has released version 1.0 of the standard specification in the Chronos group in 2014. In the embedded system, the expectation of parallel processing of WebCL is expected to increase even more in the trend of increasing number of heterogeneous multicore such as CPU core and GPU core in AP processor. At present, Samsung Webclite is provided as a prototype using Webkit version, and Nokia provides a prototype source for using WebCL in Firefox browser. Motorola also offers node-webcl.

Korean Patent Laid-Open Publication No. 2011-0130611 discloses a technology related to a web platform unit for a mobile terminal capable of linking a web-based application operating in a heterogeneous operating system layer module.

At this time, hardware can be logically reconfigured using a Java script language.

Logically reconfiguring means that, when processing a job using hardware, each part can process each step by dividing into parts corresponding to the steps performed in the job.

For example, when performing the calculation for the sum of 1 and 2, the steps of receiving the numbers (1, 2), converting 1, 2 into binary numbers, converting into binary numbers and performing addition , And a step of performing the exponentiation and then converting the decimal number to decimal number.

In this case, the logical reconstruction means that the hardware is logically reconfigured so that it can independently process the input part of numbers (1 and 2), the part to convert to binary number, the part to perform prefix, and the part to convert to decimal number .

The processing unit 102 sets each of the logic circuits in the high-speed circuit converted by the conversion unit 101 as an object of a JavaScript script, and processes jobs in the web application based on the objects.

At this time, the logic circuit, when performing a task,

Means each part independently processed.

For example, when performing the calculation for the sum of 1 and 2, the steps of receiving the numbers (1, 2), converting 1, 2 into binary numbers, converting into binary numbers and performing addition A circuit for processing the input of the number, a circuit for processing the operation for converting the binary number, a circuit for processing the operation for performing the buffer, a decimal number May be logic circuits. ≪ RTI ID = 0.0 >

If the next task is to perform the calculation for the difference between 2 and 1, the circuit performing the addition among the original circuits may be reconverted to the circuit performing the subtraction to perform another operation.

At this time, there is no restriction on the method of re-conversion. For example, when the previous operation is completed, the information converted to the high-speed circuit can be deleted and converted to a high-speed circuit corresponding to another operation.

[

The JavaScript engine 205 may be used to execute the JavaScript based application 201.

At this point, the JavaScript engine first decomposes the source of JavaScript into a series of tokens.

In addition, a connection relationship with a node can be created using a decomposed token, and a syntax tree can be generated.

Next, a byte code corresponding to the intermediate representation of the JavaScript source and the machine language can be generated using a syntax tree.
